长江中游航道整治中生态技术应用探讨

Exploration on application of eco-technology in waterway regulation project at midstream of Yangtze River

针对长江中游航道整治与水生态环境之间的矛盾,考虑航道自然条件包括周边环境、河床形态、泥沙、水流、水深、气候,以及船型、船舶密度等因素,从适应性、耐久性、经济性、生态美观以及维护管理等角度出发,将生态理念引入到航道整治中。将工程措施与生物措施相结合,并采用生态系统自我修复和人工辅助相结合的技术手段,选择了符合环保要求的材料和工艺。介绍了各种技术手段在长江中游若干河段航道整治中的实际运用情况,可为类似航道整治工程中生态技术的研究与运用提供借鉴。

According to the contradiction of the waterway regulation and river ecology,considering the natural conditions such as surrounding environment,riverbed configuration,sedimentation,flow,water depth and climate etc.,and the ship form and density,the ecological concept is introduced in waterway regulation from the aspect of suitability,durability,economical efficiency,aesthetic property and maintenance management.Through the combination of engineering and biological control measures,the methods of self-recovery and artificial supplementary are adopted and the material and techniques that meet the requirement of environment protection are selected.The application of the above techniques in waterway regulation at midstream of Yangtze River is described,which can provide reference for the study and application of similar ecological techniques in waterway regulation.
